Here is the caller graph for this function:

mx_access()

int mx_access	(	const char *	path,

Wrapper for access, checks permissions on a given mailbox.

Parameters

path	Path of mailbox

Return values

0	Success, allowed
<0	Failure, not allowed

We may be interested in using ACL-style flags at some point, currently we use the normal access() flags.

Here is the caller graph for this function:

mx_mbox_close()

enum MxStatus mx_mbox_close

(

struct Mailbox *

m

)

Save changes and close mailbox.

Parameters

m

Mailbox

Return values

enum

MxStatus

Note

The flag retvals come from a call to a backend sync function

It's very important to ensure the mailbox is properly closed before free'ing the context. For selected mailboxes, IMAP will cache the context inside connection->adata until imap_close_mailbox() removes it. Readonly, dontwrite, and append mailboxes are guaranteed to call mx_fastclose_mailbox(), so for most of NeoMutt's code you won't see return value checks for temporary contexts.
